2e9b0923ac Remove some branches in walTryBeginRead() that were 
added by check-in [ce5d13c2de] but became unreachable with the addition
of logic in check-in [18b26843] that enabled read-only clients to parse
the WAL file into a heap-memory WAL-index, thus guaranteeing that the 
WAL-index header is always available.
